IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 148,668, dated March17, 1874; application filed February 21, 1874.

To all whom it may concern:

Be it known that I, WILLIAM Cnnmus, of Paterson, in the county ofPassaic and State of New Jersey, have invented a new and usefulImprovement in Heating-Stoves, of which the following is aspecification:

Figure 1 is a vertical section of my improved. stove. Fig. 2 is across-section of the same, taken through the line 00 w w :20, Fig. 1.Fig. 3 is a cross-section of the same, taken through the line y y,Fig. 1. Fig. 4 is a cross-section of the'same, taken through the line a2, Fig. 1. Fig. 5 is a cross-section of the same, taken through the line41 c, Fig. 1.

Similar letters of reference indicate correspondin g parts.

My invention has for its object to furnish an improved heating-stove,which shall be so constructed as to pass the air to be heated in thinsheets between two metallic surfaces,both of which are heated by thepassage of the heated products of combustion, so that the air may bequickly heated, and so that all, or nearly all, the heat may beextracted from the products of combustion before they are allowed topass ofi into the chimney. The invention consists'in the combination ofthe perforated base, provided with a hollow flange or rim, the flangedcylinder, and the outer cylinder with the fire-pot, to form spaces forthe induction of cold air and the eduction of the products ofcombustion; and in the combination of the five concentric cylinders, theperforated cover, the close cover, and the three sets of pipes with thefire-pot, the flanged cylinder, and the perforated and flanged base, ashereinafter fully described.

A is the base of the stove, which rests upon short legs B, in theordinary manner, and upon which rests the lower edge of the fire-pot O.In the base A, around the lower edge of the fire pot (l, are formednumerous holes a through which the air to be heated passes. The base Ais provided around its outer edge with an inwardly-projecting flange orrim, ta the space or chamber D beneath which serves as a flue, toconduct the products of combustion to the pipe or flue E, through whichthey pass to the chimney. In the middle part of the fire pot G is placedthe grate 0, thus forming an ash-pit in the lower part of said fire-pot.The fire-pot C is surrounded by a cylinder, F, the lower edge of whichrests upon the base A, around the circle of holes a and the upper. endof which rises a little above the top of the firepot (l, and has anoutwardly-projecting flange, f, formed around its upper edge, andextending outward to the outer case or cylinder G, the lower end ofwhich rests up on the rabbeted edge of the flange or rim a The flange fhas numerous holes formed through it, through which the products ofcombustion pass into the space-H between the cylinders F and G to theflue D, and which are more numerous upon the forward part of the stove,to oounteract the rearward projection of the products of combustion fromthe effect of the draft. The products of combustion are made to passdown vertically through the space H between the cylinders F and Gr byvertical flanges f 2 formed upon the cylinder F, projecting to thecylinder G, and extending down to the top of the flange o The top of thespace I between the firepot O and the cylinder F, through which the coldair passes, is closed by a ring, J, which rests upon the upper edge ofthe fire-pot O, and has three or more holes formed in it for the passageof the air, and with which are connected the lower ends of the flattenedpipes K, the upper ends of which are connected with the space L betweenthe cylinders M and N.

As the air, now partially heated, enters the space L, it divides, partpassing up through said space, and part passing through the short pipes0 into the space P between the cylinder Q and the cylinder orcoal-reservoir It. The air passes up through the spaces L and P in thinsheets, and is exposed upon both sides to a heated metallic surface, soas to be rapidly heated. The heated air passes from the spaces L and Pinto the space S beneath the ringcover T, and escapes through holes insaid cover into the room.

The cover T rests upon the upper edge of the outer case or cylinder G,and is connected with the upper edge of the reservoir or cylinder B, andhelps support said reservoir. The lower end of the reservoir R projectsinto the fire-chamber nearly to the top of the flre pot O, and isfurther supported by a flange formed upon it, and which rests upon theflange formed upon the lower end of the cylinder Q. The up 2 3&81368 perend of the reservoir It is closed with av closely-fitting cover, U. V isa short pipe, leading from the space W between the cylinders M and G, orfrom the upper part of the fire-chamber into the upper part of the flueE, and which is provided with a damper, X.

hen the damper X is open, the products of combustion pass directly fromthe fire-chamber into the flue E, as indicated by arrows 1. \Vhen thedamper X is closed, the products of combustion pass up through the spaceY between the cylinders N and Q, through the short pipes Z, into thespace W between the the cylinders G and M, down through said space Winto the space H, and passes thence through the flue or space D into theflue E.

The stove is designed to be provided with doors, in the ordinary way 3and the cylinder G around the fire-chamber may be provided withopenings, closed with mica plates, to allow the fire to be seen. Thespaces XV andYare closed at their upper ends, and are open at theirlower ends; and the spaces L and P are closed at their lower ends, andare open at their upper ends.

The direction of the cold air, as it passes through the various spacesand becomes heated,

is indicated by arrows 3; and the direction of the products ofcombustion, when the damper X is closed, is indicated by arrows 2.

Having thus described my invention, I claim as new and desire to secureby Letters Pat ent 1. The combination of the perforated base A, providedwith a hollow flange or rim, a the flanged cylinder F f f and the outercylinder G with the fire-pot O, to form spaces 1 and H O, for theinduction of cold air and the eduction of the products of combustion,substantially as herein shown and described.

2. The combination of the five concentric cylinders R Q N M G, theperforated rin g-cover T, the close cover U, and the pipes K 0 Z withthe fire-pot O, the flanged cylinder F f f, and the perforated andflanged base A, substantially as herein shown and described.
